One of the major advantages of vinyl products is that they are easy to clean and maintain. Many consumers prefer products made from vinyl because they are highly durable. A disadvantage, however, is that vinyl products are susceptible to mildew, especially when exposed to moisture over time. Although mildew can sometimes be tough to remove, there are ways to remove it and to keep it from growing on vinyl surfaces.
Combine warm water with a little dish washing liquid in a bucket. Most mildew stains will come off with a mixture of water and a mild, nonabrasive detergent.
Moisten a soft cotton cloth or sponge in the cleaning solution and wipe the vinyl surface to remove mildew.
Rinse the vinyl surface thoroughly with clean, clear tap water before wiping dry with a soft cotton cloth.
Combine 2 cups of hot water, 3 tablespoons of white vinegar and one teaspoon of borax powder to a spray bottle to treat the more resistant mildew stains. Shake mixture well and spray onto surface. Allow to mixture sit on fabric for about 30 minutes before wiping clean with a soft cotton cloth.
Apply a few drops of undiluted liquid chlorine bleach directly to the toughest mildew stains, then scrub the spot using a medium-soft cleaning brush.
Prevent future mildew stains by treating the area with a solution of one part white vinegar and three parts water. Do this routinely to help keep vinyl surfaces mildew resistant. Since mildew forms on dirty surfaces, frequent cleaning with mild detergent and warm water can help prevent recurring mildew problems.
